JOURNAL-BOX.

SPECIFICATION forming part of Letters Patent No. I717,127, datedDecember 30, 1902.

Application filed February 7,1902. Serial No. 92,977. (No model.)

To @ZZ wir/0777, it may concern.:

Beit known that I, FREDERIC WV. SHER- MAN, a citizen of the UnitedStates, residing at Park City, in the county of Summit and State ofUtah, have invented certain new and useful Improvements inJournal-Boxes, of which the following is a specication.

My invention relates to journal-bearings; and the object thereof is toprovide a bearing-box of simple construction, great durability, and onewhich will be economical in the use of oil and practically dirt and dustproof.

To this end the invention includes a bearing-box comprising a shellhaving a cylindrical bore the major portion of which is provided with alining of Babbitt metal and end glands having neck portions fitted tothe unlined parts of the box, these glands being adjustable to aposition to provide compartments within the shell between the ends ofthe glands and thelining, in which a suitable packing may be placed.

The invention also includes other details of construction, as willappear from the following description and which will be moreparticularly pointed out in the claim.

The invention is illustrated in the accompanying drawings, in which-Figure l is a perspective View of the complete bearing-box. Fig. 2 isalongitudinalsection of the same. Fig. 3 is a transverse sectional view,and Fig. 4 is a plan view, of one section of the box. Fig. 5 is an endview of a inodied form of gland.

In the embodiment of the invention illustrated in the accompanyingdrawings and to be herein described in detail, the shell of the box isformed in two sections, a lower or base section A and a top or capsection B. The former section is made integral with a baseplate ct, andit is provided on its exterior, near each end thereof, with integralwings a and with central integral bosses or lugs a2. This section isprovided with a'central bore, semicylindrical in shape, the majorportion of which is lined with Babbitt metal, as indicated by the letterb. The sides of the shell extend above the surface of the lining andprovide flanges c, which coact with the capsection, as will behereinafter described.

The bore of the shell is considerably larger i than the shaft for whichthe box is to provide a bearing; but the bore of the lining issubstantially the same diameter as said shaft. As the lining terminatesa distance from each end of the shaft, it leaves a recess at each end ofa larger diameter than the diameter of the shaft for which the box isprovided. The capsection of the shell is provided with a similar liningd to that indicated by the letter b, and the ends of the cap-section areprovided with similar recesses to those at the ends of the base-section.This cap is provided with wings, which are intended to rest upon theupper surfaces of the lower section, and it is further provided withcentrally-arranged lugs corresponding to the bosses a2. When the cap isplaced in position, the sides thereof are inserted between the fiangesc, and the ends of the sides rest upon shoulders f on the lower section,while the longitudinal walls or sections of the lining in the cap andbase sections are made to abut each other, with interposed linerscomprising one or more strips of rubber packing. These liners areprovided so that when the Babbitt Wears one or more of the strips may betaken out to prevent any play of the'shafting in the journal-box, for,as is well-known, if a shaft is permitted to have much play it will soonpound the Babbitt metal out. rlhe bosses a2 on the lower section are`provided with threaded sockets. designed to receive the bolts h, whichpass through openings in the lugs on the cap-section and are threaded insaid sockets. These bolts serve to secure the cap firmly against thebase-section. When the cap is in place, the recesses at each endthereof, in conjunction with the recesses at each end of thebase-sections, form at each end of the box complete cylindricalcompartthrough it as to permit of the wearing away of at least threethirtyseconds of an inch of the Babbitt metal without permittingf theshaft to bear upon the inner periphery of the glands. In the normalposition of the glands when fitted in the box the ends of the necks areremoved such a distance from the end of IOO the lining as to provide acompartment at each end of the box, which is intended to receive asuitable packing, such as candle-wick, which is applied by wrapping thewick about the shaft which finds a bearing in the box. As will be noted,the packing overlies for quite a distance the spaces between the liningand the shaft at the ends of the former, so that it is practicallyimpossible for dust or dirt to pass into the ends of the box and betweenthe shaft and lining of Babbitt metal or for oil to escape from the boxexcept in very small quantities and very slowly.

'Io provide means for lubricating the bearing, an opening is provided inlthe cap-section of the shell, which extends through the lining in saidsection and is provided with distributing-ducts vformed in said lining.In this oilopening a section of pipe is threaded, which provides areservoir to receive oil and supply the same to the box, and the upperend of said pipe is closed by a suitable cap threaded thereon.

Instead of making the glands of one piece or of a single casting I maymake them in two sections, so that they may be tted to shaftingintermediate of the ends of the latter,

vwithin the ends of the shell and being pro,-

vided with a bore substantially the diameter of the shaft to bejournaled whereby an annular shoulder or flange is provided within.

each end of the shell to form the rear wall of a packing-chamber, and agland fitted to each end of said shell, the space between said shouldersand the glands being designed for the reception of packing,substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

FREDERIC W. SHERMAN.
